BioShock developer Irrational Games has just announced the Season Pass accompanying their newest entry into the franchise, BioShock Infinite. The pack will contain three pieces of post-release downloadable content—DLC which, so far, Irrational hasn't talked about. Their press release follows:

The BioShock Infinite Season Pass will be available on March 26, 2013 when the game is planned to launch, and provide nearly $30.00 of add-on content for $19.99 (PlayStation®Network, Windows® PC) or 1,600 Microsoft Points (Xbox LIVE® online entertainment network)—a savings of more than 30%. The Season Pass will include all three add-on packs, and can be pre-ordered today through www.preordernow.com or at a participating retailer.

Those who purchase the BioShock Infinite Season Pass will also receive the Early Bird Special Pack at no extra cost. This bonus pack contains four pieces of exclusive gear, a Machine Gun Damage Upgrade, a Pistol Damage Upgrade, a gold skin for both weapons and five Infusion bottles that allow players to increase their health, their shield durability or their ability to use Vigors by increasing the quantity of Salts they can carry.
